TECHNICAL FIELD

The present invention relates to a handgrip exercising device, and inparticular to a handgrip exercising device which serves to enhance auser's gripping strength with the aid of a handgrip exercise using aplurality of body parts each made of an elastic material such as siliconand further serves to selectively increase a hand gripping strength byproviding an elliptical elastic pipe in the interior, thus performing ahand gripping exercise in an optimum state depending on the strength ofa user's finger.

BACKGROUND

A handgrip exercising device is a kind of exercise devices generallyused to strengthen the muscles of a hand or a forearm and is portableand easy to use regardless of exercise places and time.

The conventional handgrip exercising device has a pair of operation armsof which one side is connected with a coil type spring, thus beingformed in an upside down V-shape. The operation arms serve elasticallyto keep a certain distance between them about the coil type spring.

In the conventional handgrip exercising device, a user grips a pair ofoperation arms with a hand and repeats gripping and ungrippingoperations, during which a coil type spring connected to one side ofeach operation arm is elastically bent. The operations that grippingforce is applied to an extent to overcome the elastic force of thespring helps strengthen the muscles of a hand or a forearm.

The conventional handgrip exercising device has a problem that grippingforce is not uniformly applied to the whole portions of each palm in thecourse of exercise due to a cylindrical rod-shaped structure of anoperation arm while a user repeatedly performs gripping and ungrippingoperations using the cylindrical shaped operation arms, as a result ofwhich a uniform muscle exercise is not performed over the whole portionsof the hand and the fingers. In worse case, a muscle pain might occurdue to a partial force concentration at a finger muscle.

The conventional handgrip exercising device is directed to performinghand muscle exercises based on the operations that one coil type springis repeatedly contracted and released. The operation arms and the coiltype spring are connected in an integrated structure, so the usershaving different strengths of hands and fingers cannot control thestrengths of a conventional handgrip exercising device.

In an attempt to overcome the above problems, a strength-controllablehandgrip exercising device is disclosed, the exercise level of which canbe adjustable based on the strength and size of a user's hand byadjusting a distance between an operation arm and a spring.

However the conventional handgrip exercising device has a problem thatforces are not uniformly applied to the whole portions of a palm when inuse due to a cylindrical rod shape of an operation arm, so a user cannotperform the uniform muscle exercise over the whole portions of a user'shand and fingers. In worse case, a finger's muscle is partially overstrengthened or loaded, thus causing a muscle pain.

SUMMARY

DETAILED DESCRIPTION OF EMBODIMENTS

The preferred embodiments of the present invention will be describedwith reference to the accompanying drawings.

As shown in FIG. 1, the handgrip exercising device 100 according to anembodiment of the present invention comprises a body part 120 formed ofa plurality of cylindrical members 110 each made of an elastic material.

The body part 120 is formed of a cylindrical member 110 made of a smoothelastic material such as a silicon material having a good grippingfeeling, so a user do a hand gripping exercise using an elastic recoveryforce of the cylindrical member 110.

As shown in FIGS. 1 and 2, it is preferred that the body part 120 isformed of three to 10 cylindrical members 110 having same diameters.

Alternatively, as shown in FIGS. 3A and 3B, the body part 120 might beformed of three to ten cylindrical members 110 having differentdiameters.

It is preferred that the cylindrical members 110 are made in a silicontube structure, the both ends of which are open for air to freely flowinto the same. However, the present invention is not limited in thisregard as other materials known to these skilled in the art to which thepresent invention pertains, may be substituted without subtracting fromthe broader aspects of the present invention.

With the aid of the structure the both ends of which are open, the bodypart 120 formed of a plurality of cylindrical members 110 can be freelyshape-transformed by a user's hand gripping force.

The handgrip exercising device 100 according to an embodiment of thepresent invention comprises an adhesive part 130 by which thecylindrical members 110 of the body part 120 are adhered in a juxtaposedshape. The adhesive part 130 is formed of a known strong bond, which iscoated on the outer surface of each cylindrical member 110, thusintegrally bonding the cylindrical members 110.

In the handgrip exercising device 100 according to an embodiment of thepresent invention, the entire diameter of the same can be adjusted onthe basis of decreasing or increasing the number of the cylindricalmembers 10, which are to be adhered by the adhesive part 130, in casethat the cylindrical members 10 have same diameters. For example, incase of an adult having a larger size hand, the large diameter “D” isneeded. In this case, six to ten cylindrical members 110 are integrallybonded using an adhesive part 120, thus easily manufacturing a largesize device.

In case of a girl or a kind having a smaller size hand, three to fivecylindrical members 110 are integrally adhered using an adhesive part130 to obtain a smaller size diameter “d”, thus manufacturing a smallersize device.

As shown in FIGS. 3A and 3B, the handgrip exercising device 100according to an embodiment of the present invention might be formed of aplurality of cylindrical members 110 having different diameters.

In the structure of different diameters, each cylindrical member 110 ofthe body part 120 comprises a larger diameter cylindrical member 110 a,and a smaller diameter cylindrical member 110 b. The cylindrical member110 can be manufactured in a larger size diameter for an adult or aperson having a larger size hand or can be manufactured in a smallersize diameter or a girl or a kid having a smaller size hand incombination with the large size diameter cylindrical members 110 a andthe smaller size diameter cylindrical members 110 b.

As shown in FIG. 4, the handgrip exercising device 100 according to anembodiment of the present invention, the hand gripping force can beadjusted by further inserting the elastic pipe 140 into the interior ofthe cylindrical member 110. The elastic pipe 140 has an elliptical crosssection and is made of the same silicon material as the cylindricalmember 110 and is tightly inserted into the interior of the cylindricalmember 110.

Since the elastic pipe 140 can elastically withstand against theoperation that the cylindrical member 110 is inwardly pressed in theinterior of each cylindrical member 110, so a user needs a larger handgripping force, and the body part 120 in which the elastic pipe 140 isengaged in the interior of the cylindrical member 110 needs a largerforce as compared to the body part 20 which does not have the elasticpipe 140. So, the above construction is good for an adult having alarger hand gripping force.

As shown in FIG. 2, a user does a hand gripping exercise, holding thebody part 120 and gripping and ungripping with the aid of the elasticrecovery force of the cylindrical members 110.

When a user holds a handgrip device 100 according to an embodiment ofthe present invention, as shown in FIG. 5A, each body part 120 formed ofa plurality of cylindrical members 110 receives a pressing force P1 inthe direction of the diameter of the body part 120, and as shown in FIG.5B, the intermediate portion of the body part 120 receiving a user'shand gripping force is pressed in the direction of the diameter, so thediameter is shape-transformed in the decreased state.

In the above state, when the use removes a hand gripping force, the bodypart 120 recovers to the initial state with the aid of the elasticrecovery force P2 of the cylindrical members 110, and the diameter ofthe intermediate portion of the body part 120 recovers.

The user can repeatedly perform the hand gripping exercise over theabove procedures in natural postures. Since the cylindrical members 110are made of smooth and elastic materials such as silicon, which feelssoft, the user can easily grip when in use. Since the cylindricalmembers 110 of the body part 120 surround the whole portions of theuser's hand in the course of exercise, griping force can be uniformlyapplied to the whole portions of the hand.

The user can do uniform muscle exercises over the whole portions of thehand while avoiding over force from being applied to a partial portionof the finger, thus basically preventing a partial muscle pain at thefinger muscles, which leads to easier hand grapping exercises.

The handgrip exercising device 100 according to an embodiment of thepresent invention might further equip with an elliptical elastic pipe140 at an inner side of each cylindrical member 110, thus selectivelyincreasing the strength of hand gripping, which results in the optimumhand gripping exercise depending on the strength of user's finger.

The body part 210 comprises a space part 230 formed of a plurality ofthrough holes 232 juxtaposed arranged in the interior in thelongitudinal direction of the body part 210, thus allowing air to freelyflow through the through holes and producing an easier shapetransformation of the body part 210 with the aid of the stored elasticrecovery force.

The handgrip exercising device 200 according to another embodiment ofthe present invention serves to provide a user with a function ofperforming a hand gripping exercise by using an elastic recovery forceof the body part 210 after the user holds the body part 210 with a handand converts into a hand gripping force.

A shown in FIG. 6, it is preferred that the handgrip exercising device200 according to another embodiment of the present invention ischaracterized in that the outer surface of the body part 210 is formedof a curved surface 214 formed at a regular interval at a certain arccurvature in the circumferential direction, and the space part 230comprises a through ole 232 formed of a plurality of circular holes 236formed in the interior of the body part 210 in the longitudinaldirection of the body part 210, and a polygonal hole 238 formed at itscenter portion.

As shown in FIG. 7, it is preferred that the body part 210 ischaracterized in that the outer surface of the body part 210 is formedof a straight polygonal surface 216 formed at a regular interval in acircumferential direction, and the space part 230 comprises a throughhole 232 formed of a plurality of circular holes 236 formed in alongitudinal direction of the body part 210 in the interior of the bodypart 210, and a polygonal hole 238 formed at its center portion.

It is preferred that the body part 210, as shown in FIG. 8, ischaracterized in that the outer surface of the body part 210 is formedof a curved surface 214 at a regular interval at an arc curvature in acircumferential direction, and the space part 230 comprises a throughhole 232 formed of a plurality of circular holes 236 juxtaposed in thelongitudinal direction of the body part 210 in the interior of the boypart 210.

It is preferred that the body part 210 is characterized in that theouter surface of the body part 210, as shown in FIG. 9, is formed of astraight polygonal surface 216 at a regular interval in a polygonalshape in a circumferential direction, and the space part 230 comprises athrough hole 232 formed of a plurality of circular holes 236 juxtaposedin the longitudinal direction of the body part 210 in the interior ofthe body part 210.

In the structure of the handgrip exercising device 200 according toanother embodiment of the present invention, as shown in FIG. 4, thespace part 230 serves to adjust the strength of hand gripping by furtherproviding the elastic pipe 140 in the interior of the through hole 232,and the elastic pip 140 is formed of an elliptical cross section and ismade of the same silicon material as the body part 210 and is tightlyand fixedly inserted into the interior of the through hole 232.

In the handgrip exercising device 200 according to another embodiment ofthe present invention, a user holds the body part 210 and performsgripping and ungripping exercises with the aid of the elastic recoveryforce generating upon the shape transformation of the space part 230.

In this case, when a user grips the handgrip exercising device 200according to another embodiment of the present invention, the space part230 formed of a plurality of through holes 232 receives the forceapplied in the direction of the diameter of the body part 210, and theintermediate portion of the body part 210 is pressed in the direction ofthe diameter and is shape-transformed in a shape that the intermediateis reduced. At this time, the space part 230 provides a space in whichthe body part 210 is shape-transformed as the internal air of the thoughholes 232 are discharged to the outside, thus easily shape-transformingthe body part 210 and storing the elastic recovery force.

In this state, when the user eliminates the gripping force, the bodypart 210 recovers to its initial state due to the inherentcharacteristics of material, and the trough holes 232 areshape-transformed and recover to their initial states.

Through the above procedures, the user can repeatedly and naturallyperform the hand gripping exercises in a state that the user cannaturally and smoothly grip the body part 210 since the body part 210 ismade of an elastic material like a silicon material which feels soft.Since the hand gripping exercise are performed with the body part 210being enough surrounded by the whole portions of the palm of the user,the gripping force can be uniformly applied to the whole portions of thepalm.

The user can do uniform muscle exercise over the whole portions of thehand and the fingers without applying a partial over load to a certainfinger muscle and causing a partial muscle pain, as a result of which itis possible to more efficiently perform a hand gripping exercise insafe.
